Distilled water is

Options

A. a mixture
B. compound
C. element
D. none of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Distilled Water**: Distilled water is water that has been purified through the process of distillation, which removes impurities and contaminants.

2. **Chemical Composition**: The chemical formula for distilled water is H2O. This indicates that it is composed of two hydrogen atoms and one oxygen atom.

3. **Classification of Substances**: To classify distilled water, we need to understand the definitions of mixtures, compounds, and elements:
- **Element**: A pure substance that cannot be broken down into simpler substances by chemical means.
- **Compound**: A substance formed when two or more elements are chemically bonded together in a fixed ratio.
- **Mixture**: A combination of two or more substances that are not chemically bonded and can be separated by physical means.

4. **Identifying Distilled Water**: Since distilled water (H2O) is made up of two different elements (hydrogen and oxygen) that are chemically bonded in a fixed ratio (2:1), it qualifies as a compound.

5. **Purity of Distilled Water**: Distilled water is considered a pure substance because it does not contain any impurities or other substances mixed in with it.

6. **Conclusion**: Therefore, distilled water is classified as a compound and a pure substance.
